LOCATION

The Mulwarrie Project tenement package contains ten tenements including M30/110, E29/1010, E37/1417-1418, E30/513, P30/1141-1143 and ELA30/511-512 (Figure 1). The project is accessed from Coolgardie via the unsealed Coolgardie North and Davyhurst-Mulline roads.

The Mulwarrie Project is located 120km WNW of Kalgoorlie, and 500km ENE of Perth in the Eastern Goldfields Region of Western Australia.

The nearby Mulline Project is located a further 15km along the unsealed Davyhurst-Mulline road, with access to the tenure via station tracks and grid lines.

The Emerald Project is located 150km NW of Kalgoorlie, 45km WNW of Menzies and 525km NE of Perth in the Eastern Goldfields Region of Western Australia (Figure 1). The project is accessed from Coolgardie via the unsealed Evanston-Menzies, Riverina-Snake Hill roads, from there using local gravel tracks and grid lines.

The Canegrass Project is located 100km NW of Kalgoorlie and 530km ENE of Perth in the Eastern Goldfields Region of Western Australia (Figure 1). The project is accessed from Ora Banda via the Goldfields Hwy, the unsealed Board Arroe-Ora Banda, Davyhurst-Ora Banda Roads, from there using local gravel tracks and grid lines.

The Camelot Project is located a 240km north of Kalgoorlie, 30km NNW of Leonora and 645km NE of Perth in the Eastern Goldfields Region of Western Australia (Figure 1). The project is accessed from Leonora via the Goldfields Hwy, and unsealed station tracks.

GEOLOGY

Regional Geology

Rocktivity’s tenements are located within the Archean aged Yilgarn Craton of Western Australia. The Canegrass, Emerald, Mulline and Mulwarrie Gold Projects are located on a western branch of the Norseman-Wiluna Greenstone Belt, locally termed the Davyhurst-Mt Ida Greenstone Belt (DMIGB). The belt is a mixture of a mafic-ultramafic and felsic volcanic sequences intruded by several large Monzogranites, one of these intrusions, the Ularring Monzogranite, straddles the boundary between the Barlee and Eastern Goldfields Superterrane Domains (Figure 2).

The Camelot Gold Project is located in the Kurnalpi Terrane of the Norseman-Wiluna Greenstone Belt, at the north-western tip of the convergence of the Murrin, Gindalbie and Menangina Greenstone Belts. The greenstones comprise of a mixture of a mafic-ultramafic, sedimentary, and felsic volcanic sequences. In addition, the project lies next to the convergence between the Keith-Kilkenny lineament and Melita-Emu Fault.

Emerald, Mulline and Mulwarrie Project Geology

The geology of the Emerald, Mulline and Mulwarrie Project’s is broadly subdivided into two distinct zones separated by the crustal scale Ida Lineament, which strikes approximately north-northwest through the project area. On the western side of the project the sequence comprises a sequence of mafic basalts of the Barlee Domain, the eastern side is comprised of mafic intrusives of the Kalgoorlie Group, Eastern Goldfields Superterrane. The mafic units have been intruded by numerous porphyry and porphyritic quartz intrusions. Minor pegmatitic intrusions have also bene mapped within the project. The 15km long and 7km wide Ularring Monzogranite, a north-west trending pluton, appears to have been emplaced during the early stages of tectonism as aeromagnetic date shows the pluton as undergone similar brittle deformation to the surrounding greenstones.
